Explanation:
Answer:
correct answer is option d (Light emitted by an element produces a unique identifying spectrum.)
Explanation:
Each element has different atomic number and atoms of an element can radiate a certain amount of energy. Different elements have different atomic spectrum and it can be used to determine the composition of a material.
When atoms are excited to higher energy state after some time they came back to lower state by emitting their excess energy in the form of light. This light has certain wavelength. This emitted light can be seen as a series of different colored lines and between two colored lines there is a dark space. This series of colored lines is called a line spectra or atomic spectra.
Answer:
The warmth you feel is the heat generated by the force of friction created by the rough surfaces of your hands rubbing together. As the abrasives in your eraser are rubbed against paper, friction produces heat, which helps the rubber become sticky enough to hold onto the graphite particles.

I hope this helps and pls mark me brainliest :)
Answer:
Zero Acceleration.
Explanation:
If an object is at equilibrium, then the forces are balanced. Balanced is the key word that is used to describe equilibrium situations. Thus, the net force is zero and the acceleration is 0 m/s/s. Objects at equilibrium must have an acceleration of 0 m/s/s.
the correct answer is no ;)
